Abstract

La présente invention concerne un procédé, un dispositif et un système d'accès par paquets en liaison descendante à haut débit (HSDPA) pour un mode duplex à répartition dans le temps (TDD) d'un système de communication sans fil, et notamment d'un réseau d'accès radio terrestre (UTRAN) d'un système universel de télécommunication mobile (UMTS). Plus particulièrement, l'invention concerne un procédé, un dispositif et un système utilisant un canal indicateur de recherche (PICH) en vue d'une signalisation d'un accès par paquets en liaison descendante à haut débit (HSDPA) pour un mode duplex à répartition dans le temps (TDD). La structure du canal indicateur de recherche (PICH) est modifiée de façon à permettre la transmission d'un indicateur de haut débit (HI) vers un dispositif de terminal mobile adressé initialisant un accès par paquets en liaison descendante à haut débit (HSDPA).
